RELEASE COATINGS FOR ELASTOMERIC STRUCTURES; COMPONENTS FOR TYRE BUILDING MACHINES; PNEUMATIC TYRES AND CONVEYOR BELTS

摘要

Elastomer structures having exposed controlled surface release characteristics can be made by coating at least a portion of their surface with a releasing composition comprising (a) a chlorosulphonated polymer; (b) a reinforcing filler and (c) a green tackifying agent. Optionally, these compositions can also contain a chemical curing system and one or more volatile solvent/diluent viscosity-reducing vehicle. In a specific example, the coating are applied to flexible structures used in machines for the manufacture of articles having natural tack due to their rubber or elastomer content.
